Decarbonisation Technology - November 2021

From the mass flow rate, fluid density and temperature measurements taken by a Coriolis meter, other measurement values can be inferred from the data, such as volumetric flow rate and percent concentration. A single Coriolis meter can therefore carry out the work of multiple instruments, saving money by reducing the need for separate devices, while also cutting down maintenance. A flow computer is an electronic device that takes inputs from the flowmeter along with pressure and temperature sensors to compute a correct volume flow. In this sense, the flow computer essentially acts as the cash register in a hydrogen custody transfer application. The software is used to continuously and intelligently validate, in real-time, field signals and raise an error condition so that appropriate actions are taken when the measurement fails. Depending on the actual root cause, in many cases it can not only detect an error and warn the operator, but it can also semi-automatically or even fully automatically correct for the mismeasurement incident and regenerate the

flow calculation results, in near real-time, without adding any further uncertainty. This means that mismeasurement incidents are now resolved in seconds, rather than in weeks, saving vast amounts of time compared to resolving issues manually. This means that paperwork can be filled out swiftly and correctly, removing barriers and complexity from the custody transfer process. In summary There is considerable appetite in increasing the use of hydrogen as a green, decarbonised alternative to traditional fossil fuels. The success of the future hydrogen economy is highly dependent on its participants having confidence in the accuracy of flow measurement. With modern measurement techniques such as Coriolis mass flow measurement, combined with advanced flow computer software, the industry is ready to accelerate into a hydrogen future.

Demand for hydrogen is expected to increase up to ten-fold by 2050 when multiple industry reports predict 8-24% of the world’s final energy demand will be supplied by hydrogen. Hydrogen has a unique ability to address ‘hard- to-decarbonise’ sectors and long-term power storage. To achieve this, it must be produced with significantly lower carbon intensity than is practised today.

Learn how customised and integrated carbon capture and hydrogen purification technology can offer: • The most cost-effective and proven routes to low carbon intensity hydrogen available today for both new and existing assets • CO 2 recovery rates of 99%+ • Tailored results to meet required H 2 and CO 2 purity requirements • Single unit separation and liquefaction • Solvent-free options with a smaller footprint
